3 FITTING THE MODBUS MODULE OPTION CARD

3.1 Inside an IQ Pro or IQT Pro actuator

The MFU is suitable for fitting into IQ Pro actuators with 3000 or 5000 series wiring diagrams and IQT
Pro with 6000 or 7000 series wiring diagrams. The connections and fitting in an IQT Pro is similar to
that for an IQ Pro and the following information effectively relates to both actuator types. The MFU is
normally located in the first option board slot inside the electrical housing using connection SK1 to the
Main pcb.

Fig 7: The IQ Pro and IQT Pro MFU and its location in an IQ Pro or IQT Pro actuator
With the IQ Pro and IQT Pro actuators the remote inputs are always present (they are conditioned by
the MFU) and there is an option to include Digital Outputs from relay contacts. If the MFU is required
to operate the 4 digital outputs that can be controlled from the card then the Extra Relay Indication
card associated with these outputs must be fitted into the actuator. The following table describes the
wiring harnesses and their function in the IQ and IQT actuator.
